Method for adjusting a brake system of a vehicle

Device for controlling a brake system for vehicles, comprising:

• a vehicle speed control unit which includes means to adjust a predetermined vehicle speed by means of an automatic intervention into a brake controller and
• means for deactivating the function of the vehicle speed control unit in the event of a simultaneous braking request from the vehicle speed control unit and a braking request of the driver, wherein the device includes means to reduce the pressure PA introduced into the wheel brake due to the braking request of the vehicle speed control unit according to a predetermined function PX in the event of the braking request of the driver, and
• means for adjusting a resulting brake pressure Pres in the wheel brake of the vehicle that is determined by the formula
• Pres=PF+PX−(PF*PX)/constant Z,
• where:
• PF is the pressure introduced into the wheel brake due to the brake request of the drive;
• PX is the pressure introduced into the wheel brake by the vehicle speed control according to a predetermined function.
